To all whom i tmay concern:

Be it known that I, HERBERT W. DREW, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Window-Ventilators, of which the following is' a specification.-

The object of my inventionis to provide a novel structure for ventilating the interior of a car or other inclosed structure that is especially adapted for use with dining cars to prevent the entrance of dust and cinders with the ventilating draft.

A further object is to provide for the deflection of air currents entering my ventilator, and to hold the deflecting member rigid in any desired position.

I obtain these results by-means of the structure shown in the drawings, in which- Figure 1 shows a perspective view of an interior ofpart of the dining car showing my ventilator in place. Figs. 2, 3 and 4 are perspectives of my improved ventilator, showing the deflectors arranged to deflect the air currents upwardly, downwardly, and

in both directions respectively. Fig. 5 is a vertical transverse section of my ventilator. Figs. 6 and 7 are detail views of my frictional socket members. Fig.'8 is a detail perspective of an outside corner of my ventilator.

Fig. 1, numeral 1, designates the lower sash of an ordinary car window with my-improved ventilator 2 in position beneath-the same showing one deflector, 3 in position to direct ventilating current upwardly. 4 designates a frame of the ventilator which has weather strips 5 or the like on its upper and lower edges to insure a tight joint between the window sash and the ventilator in position. On the under side of the upper part of the frame 5 is a groove 6, shownin Fig. 5, in which is seated the main body portion and arm 7. Holding this arm 7, seated in the groove, is a strip 8 fixed to the frame by the screws 9. This strip 8, as shown,

bears on the under side of the arm 7 and forms a frictional engagement therewith. By tightening or loosening the screws 9 the amount of friction between the strip 8 and the arm 7 may be increased or decreased. The arm 7 is provided with downwardly extending ends 10 having inwardly turned extremities 11. The deflector plates 3, which are preferably constructed of plate glass, are provided with apertures 12 (see Fig. 7) in which are inserted the necks 13 of the window by graspin socket members 14. These socket members are provided with perforations 15 and slots 16, as shown in Figs. 6 and 7. Below and at'nght angles to the apertures 15 are the threaded holes 17 in thc'socket member from which are threaded the screw members 18 for the purpose to be hereinafter described.

19 designates an internally threaded aperture in the neck 13 of the socket member.-

The washers 20 are slipped over the necks 13 before inserting the latter in the apertures 12 of the deflectoiyand when securing the socket members to the deflector, a screw member 21, carrying the washers 22 and 23, is threaded into engagement with the neck 13, as shown in Fig. 7, the whole forming a secure fastening for the socket member 14. The washers 20 and 22 are formed of some soft packing material, such as felt, and prevent the scratching of the glass deflector as well as insure the tight joint. The washer 23 is preferably of material to furnish a seat for the head of the screw threaded member 21. The extremities 11 of the arm :7 slip in the apertures 15 of the socket member, and, owing to the slot 16 in.the-- socket member extremities, are frictionally held in the apertures 15 to increase or diminish the friction of disengagement. tightened or loosened, as will be clear from the above description. The inner periphery of the frame 1 is recessed at 24 to provide a seat for the screen member25 which is retained in place by the beading strip 26.

Outlet apertures 27 extend from between the screen member 25 and the deflector 3 downwardly and outwardly. 'Cinders or dust entering with the ventilating current through the screen 25 will strike the deflector plate 3 and will fall to'the bottom of the inner part of the frame and be carried downwardly and outwardly through the apertures 27.

After securing the frame in place in the the deflector plates 3, the arm 7 will permit the outward displacement of the deflector with respect to the frame, and by rotating the deflector about the extremities 11 of the arm 7 it may be rotated into any of the desired deflecting positions shown in dotted lines in Fig. 5 of the drawings. The frictional engagement of the arm 7, with the strip 8, willserve -to hold the arm in its adjusted position, and the frictional engagement of the extremities 11, with the socket members 14, will cause the The screw member 18 is so i deflector to be retained in any of the de- 1 casing, said closure being frictionally se- I and inany one of a plurality of deflecting fleeting ositions to which it is swung, so that dra t may be deflected downwardly or upwardly, or in both directions, according to the position in which it is placed, as is shown by the positions indicated in dotted lines in Fig. 5.

I claim:

1. In a device of the class described, a casing adapted to be inserted beneath the window, said casing being provided with an aperture, a closure for said aperture, means connecting said closure to said casing, said means being also adapted to firmly hold said closure bodily displaced from said casing and in any desired deflecting posi tion about .an axis with respect to said casing.

2. In a device of the class described, a casing adapted to be inserted beneath the window, said casing being provided with an aperture, a closure for said aperture, means connecting said closure to said casing, said means being frictionallysecured to said cured to said means, whereby said closure may be held bodily displaced in said casing positions. I

3. In a window ventilator, a frame, and a deflector, said deflector being connected to said frame by an arm, said arm permitting said deflector to swing bodily outward from said frame, said arm being adapted to hold said deflector in an adjusted deflecting position with respect to said frame when said deflector is in. an outwardly displaced position.

4. In a window ventilator, a frame, an arm] hingedly connected along one portion to said frame, and a deflector, said deflector being frictionally hinged to the extremities of said arm, whereby said deflector may be rotated to any desired position about the extremities of said arm in relation to said frame and retained in such position.

5. In a window ventilator, a frame, an arm having its intermediate portion seated in a groove in said frame, a strip adjacent said groove frictionally engaging said arm to form a hinged connection between said arm. and said groove, and a deflector carried by offset extremities on said arm, said deflector being connected to said extremities by means of frictional engagement, whereby said deflector may be rotated about its engagement with said arm as an axis and held in an adjusted position in relation to said frame.

6. In a device of the class described, a frame,'anarm provided with ofl'set end portions in a groove in said frame, a stri fixed to said frame and holding saidarm in said groove, said strip being provided with the offset en means to increase or lessen the friction between it and said groove, whereby the arm when rotated may be frictionally held in any desired osition, a deflector carried by d portions of said'arm, said de flector frictionally engaging the said end portions of said arm, and means to increase and lessen the friction between said deflecto and the end portions of said arms.

'7. In a device of the class described, a frame, an arm, said. arm having a main portion and downwardly extending end portions, said end portions .being provided with inwardly turned extremities,a deflector, said deflector being frictionally engaged by the extremities of said arm, the main portion of said arm being frictionally engaged by said frame, means'to regulate the friction of said first named engagement, and means to regulate the friction of said second named frictional engagement, whereby said defiector may be held free from contact with said frame, and whereby said deflector may be rotated about the extremities of said arm as an axis of rotation and held in an adjusted deflecting position.
